T LL PRSONS 'lO `WHOM THESE PRESENTS SHALL COME:

Be it known that ne, WILLIAM L. AINswOnrH-nnd AMOS D. WRIGHT, of Lowell, in the county oi' Middlesex,

and State of Massachusettn have mede a. new and useful Invention having reference to Carding Engines and we do hereby declare the some to be fully described in the following specification, and represented in the nc'eompenyingV drawings, of which- Figure 1 is a. top view.

Figure 2, e side elevation; and A l Figure 3, creer end elevation' of the main portion of .a carding engine, with our invention applied to its feeding and laying mechanisms. Y

The nat-ure of onrinventlon consists in n. peculiar stop-motion, or stopping mechanism, andthe 'combinntion ofitond theli'eeding and laying mechanisms of the cnrding engine. The objectof oni-invention is the stoppage of the feeding mechanism when the sliver of the laying-mechanism may become broken. With thc common ccrdingengine, es provided with n laying mechanism applied to it or its feeding aprons, and being without any stop-motion or mechanism for automatically arresting the operations of the feeding mechanisms on breakage oi' the sliver while being delivered to the laying mechanism, it generally happens that the breakage is not discovered until sometime citer its occnrrence, in which case the unfilled space of the feeding aprons has to be supplied with the sliver laid in it by manuel labor. Oui-invention saves all this labor, and is advantageous in other respects.

In the drswings, A denotesf-the frame of the csrding engine;- B the mein card cylinder; l) the doier; C the feeding cylinder, and the upper of the two feed rollers. There goes around the lower feed roller,nnd o. series of smaller rollers, a da er., arranged obliqucly with respect to it, a series'oi' endless opl-ons or belts, b b b. It is on these aprons or belts that the sliver, as it proceeds from the breaker, is laid by the laying mechanism, which mcy he thus described: The sliver is shown :it S, as `led through s carriage, c, and between vtwo guide-rollers d d fixed thereon. his carriage is 'supported byor depends from s. stationary and horizontal rod, e, lixed to o. frsme,f, which is erected overnnd across the series of belts 6,6 b. The said frame carries two vrheels,f1g, about which an endless belt, 7L, travels. lA pin or stud, z', extending from the belt, goes through a. slot, k, made vertically in and through the csi-ringe vc.. The said endless belt is disposed directly in front of the carriage, and there is u. hevelled'gcnr, Z, fixed on the shaft m of its Wheel, g, Another bevel gear, n, fixed on a. shaft, o, engages with the gear l. v An endless belt, p, going around two pulleys q r (one Oirwhich is fixed' on the shaft o, and Ythe other on the shaft s of the feeding cylinder C) serves to transmit rotary motion to the shaft o sind its gear n, which in turn aetuetcs the gear l. In` this wey the endless belt obtains s. continuousA rotary motion. Such belt :ind its pin, z', will import to the carriage c a, reciproca-ting rectilinear motion, whereby the sliver will be laid first in one direction, and next in the opposite way, on the series of belts or aprons-fb b. The ymechanism for operating the lower of the feed rollers, and, as o matter of course, the series of endless nprons,'inoy he thus explained: A spur gear, t, xed on the shaft or journollu of such roller-engages with a.

pinion, zr, applied to the inner side of a. hevelled gear, :amounted on o spindle, w, projected from the side of the frame A. A long shaft, y, driven by o. train of gears, z a b' c', which derives motion from zt `spur pinion, d', fixed on the shaft of the doiicr D, carries n tubular shaft, c, and should be connected therewith by what is termed n feather connection. This tuhnlor shaft supports a. bevel pinion, s, and slides freely on the shaft y,

and is grooved transversely, as shown nt da. A fox-lz, c2, enters the said groove, und is jointed to n shipper or lever, f, nrrsnged on the side of the frame A in manner as represented in the drawings. A spring, g', applied to the frame A, ond having its free end resting against or suitably applied to the fork, serves to move the fork so as to cause it to move the shaft e, with its bevel pinion s on the shaft y, and in a manner to disengnge the said frame from the bevel gear x. 'lhe shipper serves to enable a. person to move the fork in the opposite `direction in order to 'effect the engagement of -thc pinion s" with the scid gear z. The shipper, when driven backward, springs into n notch, h', formed in n slotted pinto, z", projected from vthe freine A. A'sinall alsrnm or heil, k', 4iii-tucked to the shipper by n spring, l', serves to give warning when hre-,dinge of the sliver und stoppage of the feeding mechanism take plnce.

The mechanism for forcing the shipperfont of the .notch L may be". thus explained; Within a standard, m', is aslide, n. A vertical section of the slide n and the' standard m i'sshown in fig. 4, in which thcalida is exhibited as havinga pin, a', extending back from'it, and eing-through the standard. A spring-p', serves to move the slide in one direction away from the shipper. I` A'tr-armedlevcr, q', is carried by f hc slider; the rear arm of auch leverbeing'heaver than andso as te overbalance the others, one of'ivhch extends horizontally, While the other is bent downward at' an vacute angle with the latter, as represented in the drawings. While the 'sliver may remain unbroken, it will, during tbe`-approacl1 of its carriage toward the shipper, be carried into eontact'with the inclined arm of4 the trifarmed lever, and by being pressed against it will tilt the lever se as to prevent a projection, r', of the` carriage from b'ing forced in eontaetwith the smaller horizontal arm -of the said lever. Should breakage of the slivertake place, there will be no tilting of the tri-armed lever during an approach of the carriage, but the projection r will be carried into contact with the tri-armed lever, and will force the slider backward, in which case itspin o', by pressure against the shipper, will clisehargc'the latter from' its notch, and thereby allow the spring gi to. effect the. disengagement of the bevel gears :i: and n. On their disengagement the lower feed roller and its series of endless belts will cease to revolve, and thus there will be no further advance of the ib-rons material laid on the belts. The attendant, on hearing the sound of the bell, which will be rung at the period of stoppage of the feeding mechanism, will know that breakage of the sliver has-.taken place, and he should at once proceed to piece up the sliver and set the feeding mechanism again in operation. l y

We make no'claim to the sliver, feeding, and laying mechanisms of themselves, hilt what we do claim as Aour invention 4is as fellows; that is to say- 4 i We claim' the peculiar stop-motionor mechanism for effecting thejdisengagement of the bevel gears s and :v and l We also claim the combination of such a stop-motion, or its equivalent, and the laying and `feeding mechanisms, as' described; and

We also claim the combination of the alarm apparatus, or its equivalent, wtlrthe stop-motion and the laying and feedingi'mechanisms applied to or making part of a eardingv engine, as described, the whole being substantially as and for operation in manner and for the object or purposes as hereinbefore explained.
